description The utility model provides an aluminum alloy window frame section bar which comprises an outer frame (1), an inner frame (2) and sealing materials embedded on the outer frame (1) and the inner frame (2). The protruding part of a hard cold bridge (6) on the outer frame (1) is connected with a first soft material (4) on the inner frame (2), and a second soft material (7) on the outer frame (1) is directly connected with the aluminum alloy face of the inner frame (2). Besides, the outer frame (1) and the inner frame (2) at least comprise three layers of sealing layers, and the sealing layers are formed by soft materials and soft materials in abutting mode. The aluminum alloy window frame section bar is provided with a multi-layer protective sealing device, thereby isolating penetration of external sound in multi-layer mode repeatedly. Moreover, the sealing mode of connecting the soft materials with the soft materials in an abutting mode is larger than connecting hard materials and soft materials in terms of cont
